Title: Quality of coal for blast furnace injection

Abstract

CANMET Energy Technology Centre (CETC) has been involved in a research program to evaluate the suitability of various coals for blast furnace injection. The primary objectives of this program are to provide essential information on coal combustion in the blast furnace and to establish proper criteria for evaluating and selecting coals for blast furnace injection. The program comprises three parts. Parts one and two have been completed. To date, the program has encompassed both a theoretical assessment of cooling and coke replacement characteristics of coals using CETC`s computer model and an experimental determination of the combustibility of coals of different ranks and particle sizes as well as the influence of oxygen enrichment on burnout. The experimental part was conducted in CETC`s pilot-scale injection unit that simulates blast furnace blowpipe-tuyere conditions. Part three now being developed will incorporate results of experimental trials into a blast furnace raceway model in order to predict total combustibility of coals at different blast furnace operating conditions. This paper describes CETC`s facility and methodology of work, and presents and discusses results.
